Claims.

My invention relates to apparatus for applying liquid poison to plants.

An important object of the invention is to provide apparatus of theabove mentioned charac- 5 ter, which is adapted to apply a liquidinsecticide to the cotton plant, for destroying the boli weevil, andwhich apparatus will apply the poison, to a considerable extent, to theundersides of the leaves arid branches. A further object of theinvention is to provide apparatus of the above mentioned character whichwill bend the cotton plant forwardly, by engaging its top, withoutbreakingor injuring the same, to permit of applying the poison to theunder side of the leaves.

A further object of the invention is to provide apparatus of the abovementioned character which will feed the liquid poison by gravity, in ahighly ecient manner, to the absorbent element or mop.

A further object of the invention is to provide apparatus of the abovementioned character which may be conveniently iiushed for cleaning thesame.

A further object of the invention is to provide apparatus of the abovementioned character which is in the nature of an attachment to bemounted upon the beam of the plow or cultivator.

A further object of the invention is to provide apparatus of the abovementioned character which is both vertically and horizontallyadjustable.

Other objects and advantages of the invention will be apparent'duringthe course of the following description.

In the accompanying drawing forming a part oi this application and inwhich like numerals are employed to designate like parts throughout thesame,

bodying my invention,

Figure 2 is a side elevation, parts in elevation, of the attachmentembodying my invention,

Figure 3 is a plan view of the same, and,

Figure 4 is a vertical section through the Vlower portion of theflexible hose.

In the drawing, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 designates the beamof the plow or cultivator, equipped with the handle 6, as is well known.

My liquid applying apparatus is adapted to be installed upon the beam 5and may be used when the cotton is being plowed or cultivated. Myapparatus comprises a supporting bracket, which Figure 1 is aperspective view of apparatus emlected adjusted elevation by means of aset screw Il or the like. The vertical rod I0 is rigidly attached to aninverted U-shaped clamp I2, which receives the beam 5 and may be heldthereon by a screw I3 or the like. The horizontal tube 1 slidablyreceives a horizontal rod I4, adapted to be clamped therein in theselected horizontal position, by a set screw I5 or the like. Rigidlyattached to the free end of the horizontal rod I4 is a band I6, formedof strap iron or the like, and this band is preferably circular. Theband has separated end portions or extensions I'I, provided withoutwardly bulging intermediate semi-circular portions I8. The extensionsI'I are adjustably connected upon opposite sides of the bulging portionsI8 by bolts I9, carrying thumb nuts 20. Band I8 and its extensions areresilient. A

The band I6 is horizontally arranged and receives therein a verticalpreferably cylindrical tank or reservoir 2|, having a cover 22, providedwith a vent 22. The tank 2| nts within the band I6 and is rmly heldtherein by frictional engagement, when the inner winged nut 2U issuitably screwed up. The tank 2I has a lower downwardly tapering bottom23, the upper large end of which is covered by a strainer 24. At itslower end, the tapered bottom 23 has a tubular coupling 25, to receivethereon one end of a flexible hose 26, clamped thereon by a ring 26".This hose is bent upon itself into a general U-shape, providing verticalarms 21 and 28. The vertical arm 28 has its upper end held between theoutwardly bulging portions I8 of the extensions II.y By unscrewing theouter winged nut 20, the arm 28 may be removed from between theoutwardly bulging portions I8. It is thus seen that the tank 2l and arm21 form one arm of a U-shaped syphon, while the arm 28 constitutesl theother arm.

The intermediate curved or bent portion of the hose 26 carries anabsorbent element or mop 29, surrounding the same, and having dependingflexible absorbent elements or cords 30. A valve or petcock 3| isattached to the outer arm 28 near and above the line of sediment 32 inthe curved or bent intermediate portion of the hose 26. This valve orpetcock is preferably inclined and arranged near and above the bodyportion 29 of the absorbent element or mop, so that it discharges theliquid poison upon the body portion 29, as shown by the arrows.

The operation of the apparatus is as follows:

With the apparatus mounted upon the plow beam 5, as shown, the tank 2|is suitably illed with the liquid poison and the strainer 24 willprevent the passage into the hose 21 of large particles. Since the upperend of the arm 28 is at all times open to the atmosphere, there is notendency to create a vacuum in the U-shaped hose 26, and hence when thevalve or petcock 3| is opened, the liquid will discharge freely from thepetcock. The liquid poison passing upon the upper or body portion 29 ofthe absorbent element is transmitted to the lower portion or cords 3U ofthe mop, which become saturated with the liquid. As the beam 5 is moveddownwardly of the row of cotton, upon one side thereof, the U-shapedhose 26 engages the upper end or top of the cotton plants, bending themforwardly without breakage, and this action is followed by the cords 30of the absorbent element or mop, which will accordingly apply the liquidpoison, to a considerable extent, to the lower sides of the leaves ofthe plant. This is important, as it prevents the poison from beingreadily washed off by the rain. The valve or petcock 3| is located abovethe level of sediment, indicated at 32. When it is desired to clean thehose 26 and tank 2|, the upper end of the arm 28 is removed from betweenthe outwardly bulging portions |8, which may be effected by unscrewingthe outer Winged nut 20. The arm 28 is then horizontally arranged andWater may be poured through the tank 2| and hose 26, to flush and henceclean the same.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts, may beresorted to, without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I claim:
